Slow down, my mommy works here
Weird colors, weird font, backwards "cute and childish" 's' in "works". This is one ridiculous sign, and sadly, it's being used in a lot of places nowadays. Any traffic engineer will tell you not to put up signs that say "slow" because no one knows what exactly "slow" means! If you're slowing traffic down for a work zone, put in a temporary speed limit, not one of these monstrosities.
